New comment by rolae in "JIT-optimized Ruby can outperform a C extension"

rolae — Sat, 09 Sep 2023 07:55:12 +0000

People say the title of the article "Ruby Outperforms C: Breaking the Catch-22" is misleading, which is true, this is about Ruby code optimized by JIT outperforming a extension written in C.

But to give some context: the author Aaron Patterson is a Ruby and a Rails core team member. The article and headline is clearly targeting the ruby community, where this article has been very well received. I think it's a good title for the intended audience.

The post clarifies in the first section:

> In this post I’d like to present one data point in favor of maintaining a pure Ruby codebase, and then discuss some challenges and downsides of writing native extensions. Finally we’ll look at YJIT optimizations and why they don’t work as well with native code in the mix.

edit: added original title of the hackernews post / article

Not necessarily. Something being too fast can be confusing. If you expect a process to take some time and it ends immediately, it can feel like it failed.

I remember the people from Blogger (google) talking about this problems. People were not very familiar with blog / website builders and users were confused when their blogs got created instantly, like "This is a big deal, me getting an entire website, what happened, what went wrong? It must have aborted the process…"

Both 3.5 and 4 hallucinated according to the professor:

> Most used 3.5. A few used 4 and those essays also had false info. I don't think they used any browsing plug-ins but it's possible--it was a take-home assignment and not one they did in class.

Mine was basically ignoring all the mining, get as many food plots as possible, and focus on energy and food. Worked well against the computer, they believed there will be enough supply. But I actually bought out the warehouse and then drove prices extremely high.

So I sold food energy at a higher pricepoint than the ore. Often the AI players couldn't afford food / energy anymore and therefore their production collapsed and they did not have enough food to have enough time to change the installations on their plots.

New comment by rolae in "Live previews with Rails and Stimulus 2"

rolae — Tue, 23 Mar 2021 15:56:31 +0000

Nice. I did something similar recently with an iFrame where you have a form for configuring customer sites and it displays the preview in an iFrame.

I had to throw in some debouncing and special handling for hidden inputs, as changes to hidden inputs do not trigger a change event on the form.

In the end the markup was very simple and is very reusable (StimulusJS v1):

        
          
             My letter

This is when StimulusJS becomes really nice, when you can compose behavior in your markup with some simple data attributes. I did not think at first that I would need this controller in other places, but a couple of weeks later, I actually needed it, and was able to reuse the controller without modification for another use case.

Exactly.

Basically all you to is to call a remote procedure, which you can do by adding a simple `data-reflex="click->Todo#toggle`. In the remote method you change something about the state (for example db, redis). The server rerenders the page and morphs the difference.

If you need more control you can get it by defining which elements to render and to morph.

It looks beautiful, but please increase the contrast. Some texts are #aaa on #fff, which is almost illegible. This is an accessibility issue not just for people with impaired vision, also for people checking a page on a mobile phone on a sunny day.

Just as you did here most people who submit a Show HN give a short description of what they did in a comment. I think it would be a good addition to include the posters top level comments in the detailed view.

For people on Rails I recommend checking out https://www.heya.email/ from The guys at honeybadger. It is a paid/open source gem, that will let work with the db data instead of having to transmit all that user data to a third party.

New comment by rolae in "Matestack – Reactive UIs in pure Ruby"

rolae — Sun, 22 Nov 2020 08:43:38 +0000

Rails has very much embraced webpack and different ways to build SPA on it, with providing an API only mode and easy install webpacker install commands. Maybe for an oppinionated framework it now offers too many ways to do the frontend.

But more importantly, Rails is still insanely productive to work with. And with gems like stimulus_reflex and matestack you can get reactivity easily without having the complexity of full blown SPAs.

rolae — Sun, 22 Nov 2020 08:30:28 +0000

No, there are three layers on how to use matestack. Without reactivity, it just creates pure HTML. If you use reactive functions like :onclick, :toggle, :async, you basically configure/fill VueJS components provided by matestack. On the third layer you can write your own VueJS components in Javascript, but still use the matestack DSL to then use/configure it.

Stimulus Reflex https://docs.stimulusreflex.com/

Laravel Livewire https://laravel-livewire.com/

Phoenix LiveView https://github.com/phoenixframework/phoenix_live_view

That's where I see a lot of potential. With Stimulus Reflex I have the convenience and development speed of Rails and I can enhance it with StimulusJS sprinkles and reflexes to create great experiences for the user. The interactivity I get is enough for 90%+ of the webapps out there and the complexity to do it is far less.

Meteor.js maybe, not sure of its focus nowaday, back when I played around with it, you had basically a MongoDB that you could query and mutate on the client, everything was then synced via a pub/sub system with the server.

Reminds of an episode of the programm (audio series). [1] They used GTP-3 to generate most of the answers the AI gives in that episode.

It is generally a fascinating series, set in a fictional future, where the program took control of the world. But it is less about that future, but more of a look back on today's world from fictional future.
